Check if datetime is between a start and end datetime in another table and return the row index

[shutr3]

Hello,

I have a table of datetimes and heart rates and another table with activities and start end end datetimes. I am trying to grab all the heart rates between the start and end datetimes. The only relationahip between the table is date and it is many to many since there are multiple activites on some days.

I am trying to get the activity index value on all the rows in the heart rate table that fall between an activity start and end and be able to plot heart rate for each activity.

I have tried using merge on a modified datetime with out seconds  and then a custom column with this code:

List.DateTimes([Start Date Time], Duration.Minutes ([End Date Time] - [Start Date Time] ), #duration(0,0,1,0) )

but I get error.

I have also tried to generate rows for each minute between start and end and then merge tables but I can't get this to work.

I will try to post sample data, this is my first post here so I'm not sure how to do it. Any help would be greatly appreciated.

Sample data pasted in from csv files. In Power Query I have columns for datetime, date , time in both tables.:

index	date	start time	end time	activity
1	12/27/2021	18:23:59	18:42:43	Cycling
2	12/27/2021	18:43:17	19:04:15	Run
3	12/27/2021	19:05:15	19:17:34	Metabolic

hr date time	Heart rate

Thank you for the help. I guess I was over thinking it.

Hi @shutr3 ,

You can use Merge Queries to match date time.

Here's the solution.

1.Extract the date of [hr date time] as the matching column.

2.Merge and expand it.

3.Add a custom column to extract the time.

4.Add a custom colummn to return the index rows using IF statement.

5.For display, filter out index rows that are not empty. Below is the result.

You can download the attachment for more details.

Best Regards,

Stephen Tao
